    描述:
    (4R)-2-acetyl-4-methyl-1,2,3,4-tetrahydro-5H-pyrazino[2.1-b]quinazoline-3,6-dione一水合肼 作用下, 以 N,N-二甲基甲酰胺 为溶剂, 反应 3.0h, 以64%的产率得到(4S)-4-methyl-2,4-dihydro-1H-pyrazino[2,1-b]quinazoline-3,6-dione
    参考文献:
    名称:
    A New Route toward 4-Substituted Pyrazino[2,1-b]quinazoline-3,6-dione Systems. Total Synthesis of Glyantrypine
    摘要:
    Treatment of sodium N-(o-azidobenzoyl)aminoacylglycinates 8 with acetic anhydride afforded 1-acetyl-4-(o-azidobenzoyl)-2,5-piperazinediones 7, with complete retention of the stereochemistry. The intramolecular aza Wittig reactions of compounds 7 in the presence of tributylphosphine followed by deacetylation gave 1,2-unsubstituted pyrazino[2,1-b]quinazoline-3,6-diones 1. This route was adapted to the synthesis of both enantiomers of the alkaloid glyantrypine.
